Spectrum of metal nanoparticle use in recent years has increased rapidly. Despite such positive impacts of copper as antibacterial, antifungal, analgesic, improving the blood flow effects, cannot be overlooked that copper is a heavy metal which in living organisms is necessary in small quantities, but large quantities can cause toxicopathy and pollute the environment. That must be taken into account in product design, manufacture, use and removal. Numerous studies on metal nanoparticles impact on human and environment has shown that metal nanoparticles destroy benign bacteria species used in wastewater treatment systems for ammonia elimination [1], if penetrated into mammalian cells, they can even cause damage to the genotype [2]. This research presents copper nanoparticle coating stability during modified textile use and care, and analysis of different textile materials’ effect on the parameters of gas discharge visualization electrogramms. The overall objective of the study is to establish an alternative, less resource consuming method for measurement of textile metal coating resistance.
